Band-specific conditions

  • NB-IoT only. EARFCN is the reference grid; NB1/NB2 carrier offsets require section 5.7.3F.

Inclusive endpoints describe the reference grid. A usable carrier must also satisfy bandwidth, edge clearance, subcarrier spacing, synchronization raster, equipment and band-specific requirements. Enhanced rasters require corresponding support. Allocation edges are not automatically usable centre frequencies.

Worked downlink conversion

EARFCN 70650 maps to 757.4 MHz.

F = 757 + 0.1 × (70650 − 70646) = 757.4 MHz. The offset and lower reference frequency belong to this band and direction.

Electrical length and propagation example

At 757.4 MHz, the free-space wavelength is 39.582 cm, the half-wave length is 19.791 cm and the quarter-wave length is 9.895 cm. Free-space path loss over 1 km is 90.034 dB.

These are reference calculations, not an antenna cut length or coverage prediction. Add feeder losses, antenna gains and propagation effects in the full link budget. A band match does not identify an operator or grant permission to transmit.

Sources and version

3GPP TS 36.101 V19.6.0 (Release 19, August 2026), tables 5.5-1, 5.5H-1, 5.7.3-1 and 5.7.3H-1. Dataset 3gpp-rel19-2026-10-01; checked 2026-10-01. This page records that specification version rather than implying support in every device or country.

Bands with overlapping allocations

At least one corresponding uplink or downlink range overlaps; this does not imply equipment compatibility.
